Application filed Kay 31, 1916.

y v To all whom it may concern:

a use the same.

Be it known that I, D}; Varr lnrrnn, a citizen of the United States,residing at the town of New Milford, county of Litchfield, State ofConnecticut, have invented certain new and useful Improvements inAdjustable Chairs; and I do declare the following to be a full, clear,and exact description of the invention, such aswill enable othersskilled in the art to which it appertains to make and My inventionrelates to adjustable chairs, but more particularly has reference to achair of this description especially adapted andv constructed for thepurpose of utilizing what is known as a bustle back,

In Letters Patent No. 1,125,167, issued to me- Jan. 19,1915, I showedand described an adjustable chair equipped with the usual upholstery,and in which the lower edge of the chair back always swung above therear edge of. the chair seat, but .I found that the,

construction of this chair was not at all adaptedfor the use of a bustleback, because the upholstery would become crushed and worn by reason ofthe fact that the lower portion of the back always swung above the rearportion of the seat.

The object of the present improvement is to provide a chair whoseadjustmentsmay be made not only without crushing, or, in fact,contacting adjacent upholstered portions, but also without leaving anygap between theback and seat such as would permit of, the insertion orpinching of the clothing of'theoccupant of the chair.

f aFurtherobjects ofmy invention will appear from the descriptionhereinafter given,

' and from theaccompanying drawings which illustrate a preferredembodin'lent of my in-' vention and In which- Figure 1 isa sideelevation partly in section ofmy improved chairwith the parts in theirnormal position with the chair back in its comparatively verticaladjustment, Fig. 2 is a similar view showing the position that the partsassume" when the chair back is lowered so as to adapt the chair for thereclining of the occupant, and Fig. 3 isa front elevation of the chair,.1

Similar numerals of r ference denote like parts in theseveral figures ofthe drawing.

,lie the stationary frame of the-chair and 2 the seat having in itsforward lower edge a jog 3 which rests loosely on a cross bar 4 of thechair frame, so that said seat is capa Specification of Letters Patent.

level of the seat, and 11 are links whose ex tren'lities are pivotedrespectively to the ends of the extension and to the opposite side wallsof the seat frame. It will, of course, be understood that these linksconnect the back with the seat at opposite sides, although 1' have onlyshown one of these links in the drawings. I

12 is a coil spring whose extremities are connected res )ectively withthe back of the frame and with the lower part ofthe seat, the functionof this spring being to assist in returning the parts to normalposition,

and while this spring is not a feature that is essential to myinvention, I ]')refe1.' to use it. 1

13 is the upholstery at the u Jper part of the back and ll is theupholstery at the lower portion of the back which protrudes very muchafter the fashion of a bustle, and chairs having this sort of upholsteryare, therefore, known as bustle back chairs.

This upholstery l4 gradually decreases. in

thickness and is the thinnest at or about the point where the rear edgeof the chair seat upholstery meets the lower edge of the bus tle portion14:, and when the back of the chair is swung rearwardly the rear edge ofthe seat will be swung upwardly while at the same time the lower portionof the back will be swung both upwardly and rearwardly, the upward swingof this portion of the-back enabling the swinging moveniients 1 of theseat and back to be effected without any gap therebetweei'rwhile therearward swinging movement of the back constantly removes the bustle,upholstery 1i from contact with the upholstery of the seat, so that thead an tages of a bustle back are obtained and the adjustments madewithout the forn'lation of any gap between the rear edge of the seat andthe back and also without any crushing or friction between theupholstery.

Secured to the underside of the seat frame a UNITED far- E OFFICE;

are cross bars 15 which project laterally from said frame and abutagainst cleats 16 that are secured to the frame of the chair when saidseat has reached a horizontal position, these cleats being secured tothe inside of the chair frame at opposite sides.

Any suitable means may be employed for locking the seat and back intheir adjusted positions, a very simple embodiment of which consists ofa bracket 17 having an elongated slot 18, which bracket is secured tothe side of the seat, a short bolt 19 with a head 20 being so locatedwith respect to this bracket that the bolt extends through the slot 18while the head is in the immediate rear of the bracket, the boltfurthermore extending through an opening in the side of the frame 1 andterminating in a threaded portion, so that by driving a thumb nut 21 onthis threaded portion and against the face of any suitable striker plate22 secured to the side of the frame 1, the parts may be drawn togetherso as to lock the seat and consequently the chair back in any suitableadjusted position. Whenever the back is in its normal or uprightposition the lower outer edge of the extension 10 will abut against across piece 23 which forms a part of the chair frame and thereby preventany further inward swing of the chair back.

For the further comfort of the user of the chair I have provided anadjustable foot rest, which consists of the usual footboard 24 that ishinged at 29 to the end of a platform 25 the rear portion of whichlatter extends within the frame of the seat and rests upon a cross piece26 forming a part of said seat frame, any suitable pin 27 extendingthrough this platform 25 in the immediate rear ofthe cross piece 26 toprevent the withdrawal of the platform. The platform extends through anelongated opening 28 in the front part of the frame 1 so as to becapable of vertical movements within certain limits.

A leg support 30 is pivotally connected to the part 24 by means of alink 31, one of these links being at each side of said support and'whenin use this leg support at its free end rests upon the seat as shown atFig. 2.

By swinging the leg support 30 forward the parts will assume theposition shown in dotted lines so that theunderside of the leg supportmay serve as a support for the soles of the feet, and in this connectionit will be noted that one face of the support 30 can serve as a supportfor the feet while the other face can serve as a support for the legs ofthe occupant of the chair, thus pre- Gopies oi this patent may beobtained for five cents each. by addressing the Washington, D. 0.

venting any dirt from the soles of the shoes soiling the legs of thetrousers.

From the foregoing it will be readily understood that the pivotal pointof the back of the chair is below the horizontal level of the chairseat, and since the extension 10 of the chair back is below this seatand is connected thereto by means of the link 11, it will be readilyunderstood that the operation of my new improved chair in itsadjustments can be effected without leaving any gap between the seat andthe back and without injury to the upholstery in the slightest degree.Also, when the foot rest is not desired the part 24 may be swung tohorizontal position and the part 30 allowed to lie flat against theplatform 25, whereupon the entire foot rest structure may be pushedwithin the chair frame so that no part of the same except the rest 24can be seen, this rest then appearing flat up against the seat frame asshown at Fig. 1.' Y

Having thus described my invention what claim as new and desire tosecure by Letters Patent is:-

'1. In a chair, the'combination of a stationary frame, a seat pivotallyconnected at its front edge to the front of said frame and capable ofswinging movements from said pivotal point, integral cross bars carriedby said seat and having their; ends extending beyond the respective seatsides,

and integral cleats common to the cross bars I seat, a. bar pivoted atone end to the seat and having its other end slotted, a bolt con-'nected to the frame and extending through the slot of said-bar andhaving a head engaging the bar, and a'nut on the bolt for engaging theframe whereby to bind the bar against the frame.

3. In a chair, a frame, a seat pivoted at its front to the frame, a backpivoted to the frame, links pivoted to the back and seat, a bar pivotedat one end to the seat, and means to clamp the bar against the frame tolock same.

In testimony whereof I aifix my signature in presence of witnesses.
